What does this PR do?

Currently when there is no python on the user's PATH they see the following error when testing a Poetry project:

 ERROR   Unspecified Error (SNYK-CLI-0000)

           Error processing poetry project. [object Object]

Docs:    https://docs.snyk.io/scan-with-snyk/error-catalog#snyk-cli-0000

This PR renders the error to show up like this:

ERROR   Unspecified Error (SNYK-CLI-0000)

           Error processing poetry project. Could not find 'python' on your PATH.
           stderr: spawn python ENOENT
           stdout:

Docs:    https://docs.snyk.io/scan-with-snyk/error-catalog#snyk-cli-0000

How should this be manually tested?

Remove python from your PATH, and then test a Poetry project locally using the CLI. On main, you should see the first error above (with [object Object]), and pointing to this branch you should see the second (referencing a missing python installation).

What's the product update that needs to be communicated to CLI users?

None

Hey @thomasschafer,

thank you for improving the error mesage! Is there any chance that the plugin returns SNYK-0010 instead of a generic error?
